Box core liner system developed at the Sedimentology Research Laboratory, University of Southern California

Abstract

Marine geologists now collect many box cores for detailed analysis at onshore laboratories. Stainless steel boxes are very expensive. Consequently, few research facilities are able to purchase large quantities (25–50) of these sampling boxes. Plastic core liners have been developed and used by the Sedimentology Research Laboratory of the University of Southern California. The fundamental liner system consists of a plastic box core liner and a detachable base plate mounted on the corer spade. These liners are remarkably durable; of 22 liners constructed 2 years ago, 15 are still serviceable after heavy use on 9 cruises. One plastic liner-base plate unit costs approximately $ 15–20. This low unit cost should make it possible for most research laboratories to construct large quantities of sampling containers when necessary and still stay within working budgets.
